“If unchecked, this can become a serious public health crisis as ozone is a highly-reactive gas and can be harmful even with short-duration exposures,” said Anumita Roychowdhury, Executive Director at the CSE ALL mega cities in India, including Kolkata, Bengaluru, Mumbai, Hyderabad and Chennai, saw high concentration of ground-level ozone pollution this summer season, according to a new analysis by think tank Centre for Science and Environment (CSE). A previous analysis had shown that ozone, instead of particulate matter, was the main pollutant in Delhi’s daily Air Quality Index (AQI) on several days this summer. The new analysis by the CSE’s Urban Lab highlighted that ozone, unlike primary pollutants, is not released directly from any source. It forms through complex chemical reactions involving nitrogen oxides (NOx), volatile organic compounds (VOCs) and carbon monoxide (CO), pollutants emitted by vehicles, power plants, industries and other sources of combustion. These substances react in presence of sunlight, leading to formation of ozone at the ground level. Anumita Roychowdhury, Executive Director at the CSE, said: “If unchecked, this can become a serious public health crisis as ozone is a highly-reactive gas and can be harmful even with short-duration exposures.” She added that while cities in north India experience high ozone levels in summer due to intense heat and strong sunlight, cities in warmer climates are also seeing consistent ozone exceedance in other seasons. The current policy focus must be expanded to include improved monitoring, the mitigation of this toxic gas and a reduction in high local exposures. Ozone mitigation needs drastic control over a range of gases from vehicles, industry and all combustion sources, Roychowdhury said. Sharanjeet Kaur, deputy programme manager at the CSE’s Urban Lab, said: “Inadequate monitoring, limited data and inadequate methods of trend analysis have weakened the understanding of this growing public health hazard across cities of India. Instead of merely averaging out the levels for the city, which is the standard practice to estimate the AQI, it is also important to adequately capture the high levels of local build-up and exposures in the hotspots and design mitigation strategies accordingly.” Between March 1 and May 31 this year, Mumbai recorded ozone exceedance on 32 out of 92 days across its monitoring stations, a 42-per cent drop compared to the same period last year. The worst day in terms of spread was March 29, when eight out of 31 stations reported exceedance. The highest ground-level ozone concentration recorded was 90 micrograms per cubic metre. In Kolkata, ozone levels crossed the safe limit on 22 out of 92 days, a 45-per cent decline compared to last summer. The city also saw an overall improvement, with the average hourly ozone peak dropping by 22 per cent. Bengaluru saw ozone exceedance on 45 of the 92 days, a 29-per cent increase from last year. The worst day was March 31, when four of 14 stations recorded levels above the standard. Hyderabad recorded 20 ozone exceedance days, a 55-per cent drop compared to last summer. The highest ozone level recorded in the city was 51 micrograms per cubic metre. Chennai saw ozone exceedance on 15 days this summer. No such exceedance was reported during the same period last year. In comparison, the city had three exceedance days in 2023 and 19 in 2022. The highest level this year was 64 micrograms per cubic metre.
Context: The UN SDG Report 2025, released at the High-Level Political Forum, warns that 35% of measurable SDG targets are stagnating or reversing, with five years left to 2030. About Summary of UN SDG Report 2025: SDG 2: Zero Hunger Hunger affected 9.1% of the global population in 2023 (~713–757 million people). 2.33 billion people faced moderate or severe food insecurity in 2023. Sub-Saharan Africa: 23.2% hunger prevalence and Southern Asia: 281 million hungry. SDG 4: Quality Education 57% of targets show no progress or are regressing. School completion, foundational literacy, and gender parity remain unmet in many nations. SDG 6: Clean Water & Sanitation 2.2 billion people lack safely managed drinking water. 3.4 billion people have no access to sanitation and 1.7 billion lack hygiene access. SDG 8: Decent Work & Economic Growth Half the targets stagnated or regressed. 57.8% of workers globally are in informal employment. Youth unemployment in 2024 stood at 12.9%, 3× adult rate (3.7%). SDG 10: Reduced Inequalities Rising inequality across income, access to vaccines, digital divide, and climate vulnerability. No significant redistribution mechanisms expanded post-COVID-19. SDG 14: Life Below Water 40% of targets regressing. Ocean acidification, marine pollution, and overfishing worsening. Least funded SDG, as highlighted at UN Ocean Conference 2025. SDG 3: Good Health & Well-Being Maternal mortality and universal health coverage targets stalled. Health systems under post-pandemic strain and chronic underinvestment. SDG 12, 15, 16 (Responsible Consumption, Life on Land, Peace & Justice) 40–42% of targets off-track. Forest loss, biodiversity erosion, institutional backsliding seen in many nations. Negative Trends Identified: Climate Crisis: 2024 was the hottest year; WMO predicts an 80% chance of hotter years ahead, endangering food, water, and health security. Extreme Poverty: Over 800 million people remain extremely poor; SDG1 is off-track as 8.9% may still live in poverty by 2030. Debt & Aid Decline: A 7.1% fall in official aid in 2024 hampers SDG funding for low-income nations. SDG Financing Gap: A $4 trillion annual gap stalls SDG investments in developing countries due to limited access to affordable capital. Positive Trends Identified: HIV Infections: Global HIV cases declined 40% since 2010, marking strong gains in SDG3 health targets. Malaria Control: 2.2 billion malaria cases averted and 12.7 million lives saved since 2000 through prevention and treatment. Social Protection: Coverage now reaches over 50% of the world population, advancing inclusive welfare goals. Way Ahead: Roadmap for 2030: Reform Global Finance Architecture: Adopt the Sevilla Commitment: Expand multilateral lending, cut debt burdens. Focus on Six Key Accelerators: Transform food systems, ensure energy access, promote digital transformation. Expand inclusive education, create decent jobs, and protect climate/biodiversity. Build Resilient Data Systems: Implement the Medellín Framework for Action for data-driven SDG policies. Target Most Affected SDGs: Immediate action on SDG 2, 4, 6, 8, and 10 — with multilateral and domestic investments. Urgent Multilateralism: Recommit to collective action beyond national interest — especially in G20 and BRICS forums. Conclusion: The UN SDG Report 2025 paints a sobering picture of stagnation amid global crises. While there are islands of success, systemic transformation and urgent global cooperation are essential. Achieving the 2030 Agenda now hinges on political will, equitable finance, and inclusive governance.

Ground-level ozone pollution jumped in big Indian cities like Kolkata, Bengaluru, Mumbai, Hyderabad, and Chennai this summer, says a new Centre for Science and Environment (CSE) report. The main culprits? Sunlight mixing with emissions from cars, power plants, and factories. Ozone is a serious lung irritant Ozone isn't just a buzzword—it's a gas that can seriously mess with your lungs even after short exposure. Northern cities see sharp spikes when the heat is on; warmer metros deal with high ozone levels most of the year. Experts are urging better local tracking and tougher emission rules to help keep people safe. Bengaluru, Chennai, and Hyderabad had varying experiences Between March and May 2025, Mumbai and Kolkata actually saw about 40-45% fewer days with high ozone compared to last year. Hyderabad did even better with a 55% drop. But Bengaluru had a 29% increase in bad ozone days, while Chennai went from zero last year to 15 this time around. Clearly, each city needs its own game plan to tackle the problem.
India's mega cities, such as Kolkata, Bengaluru, Mumbai, Hyderabad, and Chennai, are grappling with high levels of ground-level ozone pollution this summer, according to new findings by the Centre for Science and Environment (CSE). The organization emphasized that if not curtailed, this pollution could grow into a significant public health concern. The research uncovered that ozone, unlike primary pollutants, is a secondary pollutant forming through intricate chemical reactions involving nitrogen oxides (NOx), volatile organic compounds (VOCs), and carbon monoxide (CO). These emissions, sourced from vehicles, power plants, and other combustion processes, react in the presence of sunlight to create ozone at Earth's surface. Anumita Roychowdhury, CSE's Executive Director, expressed concern over escalating ozone levels, particularly in north Indian cities in summers, due to intense heat. Highlighting a gap in adequate monitoring and mitigation strategy, experts call for expanded policy focus and better data analysis to manage the crisis effectively.
